Answer:
n = r - 2.5
Step-by-step explanation:
We have the following data:
7 4.5
8 5.5
10 7.5
12 9.5
Now, what we will do is what happens if we subtract each one:
7 - 4.5 = 2.5
8 - 5.5 = 2.5
10 - 7.5 = 2.5
12 - 9.5 = 2.5
The difference is always kept constant, therefore the equation would be:
n = r - 2.5

Step-by-step explanation:
Answer:
400
Step-by-step explanation:
25 times the length is 1000 m.
Let length = L
25L = 1000
L = 40
10 times the perimeter is 1000 m.
Let the perimeter = P
10P = 1000
P = 100
perimeter = 2L + 2W
2(40) + 2W = 100
80 + 2W = 100
2W = 20
W = 10
The length is 40 m, and the width is 10 m.
A = LW
A = 40 m * 10 m
A = 400 m^2
